With ultrawideband technology losing its steam, the wireless contest is narrowing to SiBEAM's WirelessHD running at 60 GHz and Amimon's Wireless Home Digital Interface (WHDI) running at 5 GHz, with Amimon's proprietary wireless technology grabbing the first big design-win for commercial products.

Next Monday (Nov. 10), when Sony Corp. rolls out in Japan an ultrathin 40-inch LCD HDTV called Bravia ZX-1, the Japanese consumer electronics giant will be relying on Amimon's proprietary wireless HD technology to wirelessly transmit and receive audio and video signals between ZX-1's display unit and its tuner.

Sony separated the ZX-1's tuner from the display so that the LCD TV display can be as slim as 9.9 mm.
